Practice problem
We have points A(1, 3), B(5, 2), C(−5, 1)A(1,\,3),\,B(5,\,2),\,C(-5,\,1)A(1,3),B(5,2),C(−5,1) and the line of reflection is ry=0r_{y=0}ry=0. What are the reflections of the these points?
A'(-1,3), B'(-5, 2), C'(5, 1)
A'(-1,3), B'(-5, 2), C'(5, -1)
A'(-1,-3), B'(-5, -2), C'(5, -1)
A'(1,-3), B'(5, -2), C'(-5, -1)
Type a concept, like “slope” or “photosynthesis”.
